"For Me, the Camera is a Sketchbook": a Quick and Low Cost Procedure for 3D Recording in situ Underwater Cultural Heritage.

Summary

Since their invention computers have affected, influenced and often eased several processes in archaeological research. Photogrammetry has long being exploited in underwater archaeology for recording in situ underwater cultural heritage. Moreover, the opportunities offered by computer vision are now being tested and fully exploited by archaeologists and heritage researchers. The present paper discloses the results of a test produced with two softwares combining Structure from Motion and Image Based Modeling algorithms to acquire a 3D model from a set of unreferenced photos. The softwares have been applied on a submerged "breakwater" and a 15 meters long steamship. The softwares have several main advantages: they are Open Source, easy to implement, relatively time saving and require little infrastructure and expedients for data capture. The present paper will present the full workflow required to obtain a photo-realistic, scaled and geographically positioned 3D model of in situ underwater cultural heritage.
